Velocipede whose frame, extending approximately horizontally, carries in its central region, situated between the front wheel mounted for rotation by a handlebar in a fork tube fastened to the frame and the rear wheel arrangement, a guide sleeve which extends approximately vertically and which receives a vertically adjustable saddle support passing through it and carrying a saddle at its top end, characterized in that the front wheel (7) is pivotally connected to the frame (2) by a forwardly extending front wheel link (3) and the rear wheel arrangement is pivotally connected to the frame (2) by a rearwardly extending rear wheel link (4), and that the front wheel link (3) and the rear wheel link (4) cooperate with top and bottom end stops (2', 3' and 16, 17 repectively) and are connected by tension spring (9) to the bottom end, lying under the guide sleeve (12), of the saddle support (11) carrying the saddle (6).

Description

Die Erfindung bezieht sich auf ein Laufrad gemäß dem Oberbegriff des Hauptanspruches. Ein derartiges Laufrad ist aus der DE-U-7 530 321 bekannt.The invention relates to an impeller according to the preamble of the main claim. Such an impeller is known from DE-U-7 530 321.

Seitdem die sogenannte "Draisine" im Jahre 1817 vorgestellt wurde, sind Laufräder bekannt. Die Draisine gilt als Vorläufer der Fahrräder und weist einen in einer bestimmten Höhe starr verbleibenden Sattel auf, der, um eine gewisse Schrittweite beim Laufen zu ermöglichen, relativ niedrig angeordnet sein muß. Dadurch sind die Füße, wenn sie sich weit vorne oder weit hinten befinden, zwar sehr stark vom Körpergewicht entlastet, in der Mitte jedoch, wo der Abstand zwischen dem Sattel und dem Boden wesentlich geringer ist als die Beinlänge des Läufers, müssen die Beine nahezu das gesamte Körpergewicht tragen.Since the so-called "Draisine" was introduced in 1817, wheels have been known. The trolley is considered the forerunner of the bicycles and has a saddle which remains rigid at a certain height and which, in order to allow a certain step size when running, must be arranged relatively low. As a result, the feet, when they are far forward or far back, are relieved of their body weight very much, but in the middle, where the distance between the saddle and the ground is significantly less than the leg length of the runner, the legs have to do almost that carry entire body weight.

Insgesamt ist der Bewegungsablauf beim Benutzen eines derartigen Laufrades so unnatürlich, daß die Entwicklung zu den Fahrrädern ging und Laufräder heute als Fortbewegungsmittel keine Rolle mehr spielen.Overall, the sequence of movements when using such an impeller is so unnatural that the development went to bicycles and impellers no longer play a role as a means of transportation.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, ein Hilfsmittel für Läufer zu schaffen, mit dem die Füße von dem auflastenden Körpergewicht entlastet werden und bei dem der natürliche Bewegungsablauf beim Laufen weitestgehend beibehalten werden kann.The object on which the invention is based is to provide an aid for runners with which the feet are relieved of the load on the body and in which the natural course of movement can be largely maintained while running.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object on which the invention is based is achieved by the features of claim 1.

Vorzugsweise wird dabei ein Laufrad verwendet mit einer Rahmenbrücke, an der der Sattel befestigt ist sowie zwei vertikal um horizontale Achsen drehbare Schwingen, die an ihren bodenseitigen Enden jeweils ein Rad aufweisen, wobei die beiden Schwingen miteinander durch Federelemente verbunden sind.In this case, an impeller is preferably used with a frame bridge to which the saddle is attached and two rockers which can be rotated vertically about horizontal axes and which each have a wheel at their bottom ends, the two rockers being connected to one another by spring elements.

Eine höhenverstellbare Befestigung des Sattels bietet dabei die Möglichkeit, die Verwendung des Laufrades den unterschiedlichsten Körpergrößen anzupassen.A height-adjustable fastening of the saddle offers the possibility to adapt the use of the wheel to a wide range of body sizes.

Eine höhenverstellbare Festlegung der Federelemente im mittleren Bereich zwischen den beiden Schwingen ermöglicht eine verschiedenartige Vorspannung der Federn zu erzielen und damit die Anpassung des Laufrades an verschiedene Körpergewichte.A height-adjustable fixing of the spring elements in the middle area between the two rockers enables the springs to be pretensioned in different ways and thus to adapt the impeller to different body weights.

. Vorteilhafterweise weist ein erfindungsgemäßes Laufrad die Abwärtsbewegung der Schwingen begrenzende Anschläge auf, um eine zueinanderführende Bewegung der beiden Schwingen zu begrenzen, wenn das Laufrad entlastet ist.. An impeller according to the invention advantageously has stops which limit the downward movement of the rockers in order to limit a movement of the two rockers which leads to one another when the impeller is relieved.

Weiterhin weist das Laufrad vorteilhafterweise die Aufwärtsbewegung der Schwingen begrenzende Anschläge auf, damit bei einer starken Belastung die Sattelfläche nicht bis in Bodennähe durchsacken kann.Furthermore, the impeller advantageously has stops that limit the upward movement of the rockers, so that the saddle surface cannot sag down to near the ground under heavy loads.

Dadurch, daß die Räder nachlaufend an den Schwingen angeordnet sind, wird eine gute Spurstabilität des Laufrades erreicht.The fact that the wheels are arranged in a trailing manner on the rockers ensures good tracking stability of the wheel.

Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen definiert.Further advantageous refinements are defined in the subclaims.

Die Zeichnung zeigt ein Ausführungsbeispiel eines erfindungsgemäßen Laufrades.The drawing shows an embodiment of an impeller according to the invention.

In der Zeichnung ist mit 1 ein Laufrad bezeichnet, welches einen Rahmen aufweist, der aus einer Rahmenbrücke 2 besteht, an der eine vordere Schwinge 3 und eine hintere Schwinge 4 vertikal drehbar um horizontale Achsen 12, 14 befestigt sind. Weiterhin ist an der Rahmenbrücke 2 eine nach vorne weisende Lenkerhalterung 5 befestigt sowie ein Sattel 6.In the drawing, 1 denotes an impeller which has a frame which consists of a frame bridge 2 to which a front rocker arm 3 and a rear rocker arm 4 are fastened in a vertically rotatable manner about horizontal axes 12, 14. Furthermore, a handlebar bracket 5 pointing forward is attached to the frame bridge 2, as is a saddle 6.

Die beiden Schwingen 3 und 4 weisen an ihren bodenseitigen Enden ein Vorderrad 7 bzw. ein Hinterrad 8 auf und sind miteinander durch Federelemente in Form von Gummispannfedern 9 verbunden. Die Gummispannfedern 9 führen jedoch nicht direkt von der vorderen Schwinge 3 zur hinteren Schwinge 4, sondern sind im wesentlichen in ihrem mittleren Bereich an einem höhenverstellbar ausgebildeten Einstellrohr 10 festgelegt.The two rockers 3 and 4 have at their bottom ends a front wheel 7 and a rear wheel 8 and are connected to one another by spring elements in the form of rubber tension springs 9. The rubber tensioning springs 9 do not, however, lead directly from the front rocker 3 to the rear rocker 4, but are essentially fixed in their central area on a height-adjustable adjusting tube 10.

Das Einstellrohr 10 ist mit einer schellenartigen Klemmeinrichtung höhenverstellbar an einem Sattelrohr 11 befestigt, welches in einem Führungsrohr 12 innerhalb der Rahmenbrücke 2 höhenverstellbar geführt wird.The adjusting tube 10 is fastened in a height-adjustable manner with a clamp-like clamping device to a seat tube 11, which is guided in a height-adjustable manner in a guide tube 12 within the frame bridge 2.

Durch diese voneinander unabhängige Höhenverstellbarkeit sowohl des Sattels 6 als auch der Gummispannfedern 9 wird erreicht, daß die Höhe des Sattels in Abhängigkeit von der Größe des Benutzers eingestellt werden kann und daß unabhängig von dieser Größe eine Anpassung an die unterschiedlichen Gewichte der Benutzer dadurch erzielt werden kann, daß die Vorspannung der Gummispannfedern 9 durch eine verschieden hohe Anordnung des Einstellrohres 10 verändert werden kann. Wird zum Beispiel das Einstellrohr 10 weit nach oben bewegt, so werden die Gummispannfedern 9 gegenüber dem in der Zeichnung dargestellten Zustand entlastet, so daß die Gummispannfedern 9 früher ansprechen und weicher wirken, was bei der Benutzung durch leichtere Personen wünschenswert ist.This independent height adjustment of both the saddle 6 and the rubber tension springs 9 ensures that the height of the saddle can be adjusted depending on the size of the user and that regardless of this size an adaptation to the different weights of the users can be achieved that the bias of the rubber tension springs 9 can be changed by a different height arrangement of the adjusting tube 10. For example, if the adjusting tube 10 is moved far upward, the rubber tension springs 9 are relieved of the condition shown in the drawing, so that the rubber tension springs 9 respond earlier and act softer, which is desirable for use by lighter persons.

Wird dagegen das Einstellrohr 10 weiter nach unten gedrückt, so werden die Gummispannfedern 9 vorgespannt, was bei der Benutzung des Laufrades durch schwerere Personen vorteilhaft ist.If, on the other hand, the adjusting tube 10 is pressed further down, the rubber tensioning springs 9 are preloaded, which is advantageous for heavier persons when using the impeller.

Diese voneinander unabhängige Anpaßbarkeit an sowohl die Größe als auch das Gewicht des Läufers kann abweichend von der in der Zeichnung dargestellten Anordnung auch dadurch bewirkt werden, daß nicht das Sattelrohr 11 durch das Führungsrohr 12 weit hindurchgeht und unten das Einstellrohr 10 trägt, sondern daß beispielsweise das Sattelrohr 11 kürzer als in der Zeichnung dargestellt ausgebildet ist und aus dem unteren Ende des Führungsrchres 12 nicht herausragt und daß dafür das Führungsrohr 12 länger ausgebildet ist, so daß das Einstellrohr 10 direkt an dem Führungsrohr 12 befestigt ist.This mutually independent adaptability to both the size and the weight of the rotor can be effected, in deviation from the arrangement shown in the drawing, in that the seat tube 11 does not go far through the guide tube 12 and carries the adjusting tube 10 at the bottom, but rather, for example, that Seat tube 11 is shorter than shown in the drawing and does not protrude from the lower end of the guide tube 12 and that the guide tube 12 is longer, so that the adjusting tube 10 directly on the Guide tube 12 is attached.

Um die Drehbewegungen der Schwingen 3 und 4, die um Achsen 14 und 15 verlaufen, zu begrenzen, damit nicht durch die Spannung der Gummispannfeder 9 die beiden Schwingen 3 und 4 in eine nahezu senkrechte Stellung gezogen werden, sind im Inneren der Rahmenbrücke 2 verstellbare Anschläge 16 und 17 vorgesehen. Eine Veränderung dieser Anschläge 16 und 17 bewirkt sowohl eine Veränderung der Federvorspannung dadurch, daß die Weite zwischen den beiden Schwingen 3 und 4 verändert wird, als auch eine Veränderung der Sattelhöhe dadurch, daß bei einer Spreizung der Schwingen 3 und 4 die Sattelhöhe abnimmt.In order to limit the rotary movements of the rockers 3 and 4, which run around axes 14 and 15, so that the two rockers 3 and 4 are not pulled into an almost vertical position by the tension of the rubber tension spring 9, there are 2 adjustable stops inside the frame bridge 16 and 17 provided. A change in these stops 16 and 17 causes both a change in the spring preload by changing the width between the two rockers 3 and 4, and a change in the saddle height in that the saddle height decreases when the wings 3 and 4 spread.

Um andererseits aber auch zu verhindern, daß bei besonders schwerer Belastung die Schwingen soweit auseinandergespreizt werden, daß das Einstellrohr 10 bzw. das Sattelrohr 11 den Boden berühren würde, ist im oberen Bereich der Rahmenbrücke 2 für die hintere Schwinge 4 ein Anschlag durch den waagerechten Bereich der Rahmenbrücke 2 gegeben und für die vordere Schwinge 3 besteht der Anschlag in einem oberen Lenkhebel 18 im vorderen Bereich der Lenkerhalterung 5.On the other hand, however, to prevent the wings from spreading apart so far under particularly heavy loads that the adjusting tube 10 or the seat tube 11 would touch the ground, there is a stop in the upper region of the frame bridge 2 for the rear rocker 4 through the horizontal region given the frame bridge 2 and for the front swing arm 3, the stop is in an upper steering lever 18 in the front region of the handlebar bracket 5.

Der obere Lenkhebel 18 ist mit einem Lenker 19 verbunden und dreht sich mit diesem um eine senkrechte Achse. Ein unterer Lenkhebel 20, der mit dem um eine senkrechte Achse drehbar gelagerten Vorderrad 7 fest verbunden ist, wirkt mit dem oberen Lenkhebel 18 zusammen, da die beiden äußeren Enden eines jeden Lenkhebels mit den entsprechenden äußeren Enden des anderen Lenkhebels längenveränderlich verbunden sind.The upper steering lever 18 is connected to a handlebar 19 and rotates with it about a vertical axis. A lower steering lever 20, which is fixedly connected to the front wheel 7 rotatably mounted about a vertical axis, cooperates with the upper steering lever 18, since the two outer ends of each steering lever are connected to the corresponding outer ends of the other steering lever in a variable length.

Diese längenveränderliche Verbindung besteht aus einer Kette 21, die im Bereich des unteren Lenkhebels 20 jeweils eine Zugfeder 22 aufweist, so daß der Abstand zwischen den beiden Lenkhebeln veränderlich ist. Da die Achse 14 und der obere Lenkhebel 18 sich im wesentlichen auf gleicher Höhe befinden, würde der Abstand zwischen dem oberen Lenkhebel 18 und dem unteren Lenkhebel 20 in etwa der Länge der vorderen Schwinge 3 entsprechen, wenn diese senkrecht nach unten weisen würde. Sobald die vordere Schwinge 3 aber im wesentlichen waagerecht ausgerichtet ist, ist der Abstand zwischen dem oberen Lenkhebel 18 und dem unteren Lenkhebel 20 um das Maß kleiner als die Länge der vorderen Schwinge 3, welches dem Abstand zwischen dem oberen Lenkhebel 18 und der Achse 14 entspricht. Bei einer Federbewegung des Laufrades verändert sich die Stellung der vorderen Schwinge 3 und damit ändert sich auch der Abstand zwischen dem oberen Lenkhebel und dem unteren Lenkhebel 20. Neben der abgebildeten Ausführungsform wäre eine Übertragung der Lenkbefehle beispielsweise durch teleskopierende Rohre od. dgl. auch möglich.This variable-length connection consists of a chain 21, each of which has a tension spring 22 in the region of the lower steering lever 20, so that the distance between the two steering levers is variable. Since the axle 14 and the upper steering lever 18 are essentially at the same height, the distance between the upper steering lever 18 and the lower steering lever 20 would correspond approximately to the length of the front rocker arm 3 if it were to point vertically downwards. As soon as the front rocker arm 3 is aligned substantially horizontally, the distance between the upper steering arm 18 and the lower steering arm 20 is smaller than the length of the front rocker arm 3, which corresponds to the distance between the upper steering arm 18 and the axle 14 . With a spring movement of the impeller, the position of the front rocker 3 changes and thus also the distance between the upper steering lever and the lower steering lever 20 changes. In addition to the illustrated embodiment, transmission of the steering commands, for example by telescopic pipes or the like, would also be possible.

Da beim Laufen normalerweise die Hände im wesentlichen senkrecht gehalten werden, weist der Lenker 19 senkrechte Bereiche 23 auf, so daß die Handhaltung des Läufers beim Benutzen des Laufrades ebenfalls senkrecht sein kann. Es sind jedoch auch andere Handhalterungen möglich. Für diese bevorzugte Handhaltung griffgünstig angeordnet ist ein Bremshebel 24 zum Betätigen einer auf das Hinterrad 8 wirkenden Bremse 25 mittels eines Bowdenzuges.Since the hands are normally held essentially vertically when running, the handlebar 19 has vertical regions 23, so that the hand position of the runner can also be vertical when using the impeller. However, other handholders are also possible. A brake lever 24 for actuating a brake 25 acting on the rear wheel 8 by means of a Bowden cable is arranged within easy reach for this preferred hand position.

Um neben der laufgerechten Handhaltung den Bewegungsablauf des Laufens so wenig wie möglich zu beeinträchtigen, weist der Sattel 6 eine langgestreckte schmale Form auf und wird durch ein lederumhülltes luftgefülltes Kissen gebildet, dessen Härte durch unterschiedlichen Luftdruck verstellbar ist, wobei die dazu notwendigen Ventilmittel od. dgl. nicht dargestellt sind.In order to impair the movement of running as little as possible in addition to the correct hand position, the saddle 6 has an elongated narrow shape and is formed by a leather-covered air-filled cushion, the hardness of which can be adjusted by different air pressure, the necessary valve means or the like are not shown.

Eine den Sattel tragende Rahmenkonstruktion 26 weist an ihren beiden längsseitigen Enden lösbare Befestigungsmittel in Form von Schrauben 27 auf, mit deren Hilfe der eigentliche Sattel 6 aus der Rahmenkonstruktion 26 entfernbar festgelegt wird, so daß ein Austauschen gegen einen anderen Sattel mit beispielsweise anderer Oberfläche oder anderem Innenelement ermöglicht wird.A saddle-supporting frame structure 26 has at its two longitudinal ends releasable fastening means in the form of screws 27, with the help of which the actual saddle 6 is fixed removably from the frame structure 26, so that an exchange for another saddle with, for example, a different surface or other Interior element is made possible.

Die Anordnung der beiden Räder 7 und 8 an den bodenseitigen Enden der Schwingen 3 und 4 erfolgt über um senkrechte Achsen 28 drehbar gelagerte Gabeln 29, die so gestaltet sind, daß die Räder 7 und 8 nachlaufend angeordnet sind, so daß eine selbständige Spurstabilisierung der Räder während des Laufens erfolgt.The arrangement of the two wheels 7 and 8 at the bottom ends of the rockers 3 and 4 takes place via forks 29 which are rotatably mounted about vertical axes 28 and which are designed such that the wheels 7 and 8 are arranged in a trailing manner so that the wheels are independently stabilized done while running.

Mit einem derartigen Laufrad ist nicht nur eine sehr gute Anpaßbarkeit des Federverhaltens an das jeweilige Gewicht des Läufers möglich, sondern es ist auch möglich, ein Laufrad zum Trainieren des Laufens zu benutzen, beispielsweise nach schweren Operationen, wobei der Patient mehrere Wochen oder Monate gelegen hat. Zu diesem Zweck kann die Federvorspannung so hart eingestellt werden, daß das vom Patienten selbst zu tragende Körpergewicht sehr gering ist und dieser Anteil des selbstzutragenden Gewichtes kann im Laufe der Zeit nach und nach gesteigert werden, bis der Patient aus eigener Kraft wieder vollkommen sicher gehen kann.With such an impeller, not only is a very good adaptability of the spring behavior to the respective weight of the runner possible, but it is also possible to use an impeller to train running, for example after heavy operations, with the patient lying for several weeks or months . For this purpose, the spring preload can be set so hard that the body weight to be borne by the patient himself is very low and this proportion of the self-supporting weight can gradually be increased over time until the patient can walk again completely safely on his own .

Um bei derartigen Einsätzen des Laufrades die Sicherheit des Patienten weiter zu erhöhen, ist es möglich, statt des hinteren Rades 8 eine Achse durch die hintere Gabel 29 zu stecken, an deren beiden Außenseiten sich jeweils ein Rad befindet, so daß das Laufrad nicht mit zwei, sondern mit drei Rädern auf dem Boden aufsteht und damit kippsicher ausgebildet ist. Ebenfalls ist es möglich, zusätzlich zum Hinterrad 8 zwei Stützräder auf jeder Seite des Laufrades anzubringen, so daß die Funktion der Bremse 25 auf das Hinterrad 8 nicht eingeschränkt wird und eine erwünschte Kippsicherheit ebenfalls erzielt wird.In order to further increase the safety of the patient in such applications of the impeller, it is possible, instead of the rear wheel 8, to put an axle through the rear fork 29, on the two outer sides of which there is one wheel each, so that the impeller does not have two , but stands on the floor with three wheels and is thus designed to be stable. It is also possible, in addition to the rear wheel 8, to mount two support wheels on each side of the impeller, so that the function of the brake 25 is not restricted to the rear wheel 8 and a desired stability against tipping is also achieved.

Bei den unterschiedlichen Einsatzmöglichkeiten des Laufrades zu sportlichen oder auch therapeutischen Zwecken ermöglicht das Laufrad in jedem Fall die Beibehaltung des natürlichen Bewegungsablaufes beim Laufen dadurch, daß es die Auf- und Abbewegung des Läufers durch ein Einfedern der Sattelhöhe mitvollzieht. Dabei können die Füße des Läufers vom auflastenden Körpergewicht weitestgehend entlastet werden, so daß das Zurücklegen von langen Strecken oder von Strecken mit hoher Geschwindigkeit für Sportler bzw. das Laufeniernen für rekonvalestierende Patienten durch das Laufrad wesentlich erleichtert wird.With the different uses of the impeller for sporty or therapeutic purposes, the impeller makes it possible in any case Maintaining the natural course of movement when running by taking the up and down movement of the runner by compressing the saddle height. The feet of the runner can be largely relieved of the burdening body weight, so that the covering of long distances or distances at high speed for athletes or running for convalescent patients is made much easier by the impeller.
